Description

Juicer {JUICE EXTRACTOR}

The present invention relates to a juicer, and more specifically, it can prevent the screw from twisting (sag, etc.) due to its own weight, thereby reducing vibration and noise, and can simplify the structure by discharging waste in the axial direction. It's about a juicer.

In general, a juicer is a device that crushes and compresses food ingredients (vegetables, fruits, grains, etc.) while transporting them, and then discharges them to the outside through a juice container. Due to the diversification of consumers' needs, various functions in addition to juice are being added.

A conventional juicer includes a housing with an inlet at the top and a liquid outlet and a waste outlet at the bottom, a screw rotatably installed inside the housing and with a spiral protrusion formed on the outside, and a screw on one axial side of the screw. It consists of a driving part that transmits rotational force and a juice net that is coupled to the outside of the screw to generate juice from the food ingredients and separate and discharge the juice and residue.

However, in conventional juicers, the rear end of the screw is supported while connected to the driving part, so the front end of the screw sags under its own weight or flows in the direction of rotation, and the twisted screw generates vibration and noise beyond an appropriate level. This was often the case, and if a large amount of rotation was applied to the screw during the juicing process, the rotational vibration of the screw was bound to become even greater.

In addition, in the conventional juicer, the waste of food ingredients is discharged in a lengthwise state, so the waste often escapes to the outside of the container, and the discharge direction must be changed to prevent the waste from escaping to the outside of the container or to the inside of the container. There was the inconvenience of having to cut it to a certain length so that it could be inserted.

Prior literature related to the present invention includes Korean Patent Publication No. 10-2014-0084045 (July 4, 2014), which discloses a juicer in which the housing can be easily assembled and separated.

The purpose of the present invention is to provide a juicer that can prevent distortion (sag, etc.) of the screw due to its own weight, reduce vibration and noise, and simplify the structure by discharging waste in the axial direction.

The juice juicer according to the present invention has a housing in which an internal flow path penetrates forward, an upper inlet and a lower liquid outlet communicate with the flow path, and is coupled to the front end of the housing, and an internal passage penetrating forward and backward is connected to the flow path. A drum cap in communication, a juice pipe coupled to the inside of the flow path, a juice passage with cutting protrusions protruding on the inner circumferential surface penetrating in the front and rear directions, and a plurality of juice discharge holes formed in the front area, and a front end of the drum cap. It is coupled to a cylindrical connecting pipe protruding rearward, a finishing cap through which a residue discharge port penetrating before and after the connecting pipe communicates with the juice passage through the passage, and a horizontal rotation in the forward and backward directions inside the juice passage. A screw that is rotatable about the center, has a spiral protrusion protruding from the outer peripheral surface to extend in a spiral along the axial direction, and transmits a rotational force through the rear end, and protrudes from the front end of the screw to extend the length in the radial direction of the screw. It is characterized in that both ends in the longitudinal direction include cutting blades that are slidably and rotatably in close contact with the inner peripheral surface of the waste discharge port.

In addition, the cutting blade may further include a pair of contact surfaces that protrude from both ends in the longitudinal direction and are curved on both sides in the width direction to correspond to the inner peripheral surface of the waste discharge port.

In addition, it may further include a contact member that is coupled to the inner peripheral surface of the connection pipe, has a cylindrical shape through which the waste discharge port penetrates front and rear, and is made of a plastic material.

In addition, it is coupled to the front end of the juice pipe and is in close contact with the rear end of the contact member, has a ring shape with a hollow penetrating front and rear, and may further include a ring-shaped front sealing member made of an elastic material to be elastically deformable. .

In addition, the contact member is coupled to correspond to the inner peripheral surface of the connection pipe, has a cylindrical insertion portion through which the waste discharge port passes forward and backward, and extends radially from the rear end of the insertion portion to be caught at the rear end of the connection pipe. , the rear end may include a locking portion in close contact with the front end of the front sealing member.

The present invention is a structure that can rotatably support both sides of the screw in the axial direction, preventing twisting (sag, etc.) of the screw due to its own weight, thereby reducing rotational vibration and noise, and reducing food ingredients generated during the juicing process. The waste can be discharged in the axial direction of the screw, simplifying the discharge structure of the device, and the cutting blade can cut the waste to a certain length, making it easy to collect and dispose of the waste.

In addition, in the present invention, since the cutting blade rotates in close contact with the contact member made of plastic, the rotation noise of the screw and the generation of metal powder can be minimized, and since the cutting blade is rotated in the process of discharging food waste, there is a waste discharge outlet. Clogging does not occur, and the rotating grinding action of the cutting blade is continuous, which has the effect of reducing the particle size of the residue.

Referring to FIGS. 1 to 13, the juicer according to the present invention can rotate and juice food ingredients (vegetables, fruits, etc., 10) and separate and discharge the juice (L) and residue (S) in different directions, and the housing It includes (100), a drum cap (200), a juice pipe (300), a finishing cap (400), a screw (500), a cutting blade (600), and a driving unit (700).

The housing 100 is formed with a flow path 110 having a front and rear length inside, and the flow path 110 can pass horizontally forward, and the upper inlet 120 and the lower liquid outlet 130 are formed into a flow path ( 110). Here, the housing 100 can be manufactured using a metal material such as stainless steel, and the rear end of the drum cap 200, which will be described later, can be coupled and separated from the front end of the housing 100.

The inlet 120 is for injecting food ingredients (vegetables, fruits, etc., 10), and can penetrate perpendicularly to the rear area of the passage 110. At the top of the housing 100, there is an inlet pipe having a length in the vertical direction. This can be connected, and the inlet 120 can penetrate vertically into the inside of the inlet pipe. In this case, a hopper whose diameter gradually increases toward the top may be formed at the top of the input pipe.

The discharge port 130 is for discharging the juice (L) of the food material 10 generated inside the flow path 110 to the lower portion, and is vertically penetrated through the bottom of the housing 100 and communicates with the flow path 110. , It is located in front of the input port 120 to discharge the juice (L) generated when pressing the food material 10 introduced through the input port 120 to the lower part of the housing 100, and pressurizes the food material 10. The juice L generated in the process may be moved to the lower part of the flow path 110 by its own weight and then fall to the lower part of the housing 100 through the outlet 130.

For example, when the food material 10 is introduced into the flow path 110 through the inlet 120, the food material 10 is seated in the rear area of the screw 500, which will be described later, as shown in FIG. 3, and the screw 500 By rotation, the food material 10 is moved to the front of the flow path 110, and the food material 10 passing between the screw 500 and the juice pipe 300, which will be described later, is pressurized and pulverized to generate juice L. do.

The drum cap 200 is intended to open and close the front of the flow path 110, and is coupled to the front end of the housing 100, and the internal passage 210 passing forward and backward communicates horizontally with the front of the flow path 110, It may have a cylindrical shape with edges forming a circle.

Here, the drum cap 200 can be manufactured using a metal material such as stainless steel, and the rear end of the drum cap 200 and the front end of the housing 100 are locked or unlocked when rotated in the locking or unlocking direction. Male and female locking structures can be applied separately.

The juicer according to an embodiment of the present invention protrudes with a smaller diameter from the rear end of the drum cap 200, the passage 210 penetrates forward and backward, and the rear end of the drum cap 200 is in close contact with the front end of the housing 100. The insertion tube is inserted male and female through the front of the flow path 110, the outer locking protrusions protrude from the outer circumferential surface of the insertion tube and are arranged in a plurality spaced apart along the outer circumferential surface of the insertion tube, and the inner circumferential surface of the flow path 110. A ring shape that protrudes and is arranged in a plurality of spaced ways along the inner peripheral surface of the flow path 110, is in close contact between the front end of the housing 100 and the rear end of the drum cap 200, and has a hollow hole penetrating back and forth. It may further include a ring-shaped central sealing member 230 made of an elastic material (rubber, silicone, etc.) to enable elastic deformation.

For example, when the rear end of the drum cap 200 is brought into close contact with the front end of the housing 100, the insertion tube is inserted through the front of the flow path 100 and at the same time, the outer locking protrusions pass through the gap between the inner locking protrusions to form the flow path. Entering the inside of (110), the outer locking protrusions are positioned alternately behind the inner locking protrusions, and the rear end of the drum cap 200 and the front end of the housing 100 are located at the front and rear ends of the central sealing member 230, respectively. It adheres closely.

On the other hand, when the drum cap 200 is rotated in the disengaging direction, the outer locking protrusions are positioned in the gap between the inner locking protrusions, so the drum cap 200 can be separated toward the front of the housing.

The juice pipe 300 is for pressurizing the food material 10, is coupled to the inside of the flow path 110, and has a juice passage 310 with cutting protrusions 320 protruding on the inner circumferential surface that penetrates in the front and rear directions. A plurality of juice discharge holes 330 are formed in the front area of 300. Here, the juice pipe 300 may have a cylindrical shape with an outer peripheral surface and an inner peripheral surface forming a circumference, and may have a shape whose diameter gradually decreases toward the front, and may be manufactured using a metal material such as stainless steel.

In addition, the inlet-side discharge network 340 may protrude at the rear end of the juice pipe 300. The inlet-side discharge network 340 may be positioned horizontally below the juice passage 310, and moisture A plurality of inlet-side discharge holes 341 penetrate upward and downward to discharge to the bottom, and may be located on the same line at the top of the liquid discharge port 130 to prevent debris, etc. from being discharged to the outside.

That is, since the juice passage 310 is formed to slope downwardly toward the rear, the juice (L) generated within the juice passage 310 is moved downward by gravity and then falls to the upper part of the inflow-side discharge network 340. It may be that the juice (L) that falls to the top of the inlet side discharge network 340 falls to the liquid outlet 130 through the inlet side discharge hole 341 and is discharged to the lower part of the housing 100. .

Since the juice passage 310 has a shape whose diameter gradually decreases as it goes forward, it has a structure that can concentrate the food ingredients 10 moving toward the front of the juice passage 310 at the center position while applying a pressing force, The juice L generated by pressurizing the food material 10 falls to the bottom of the flow path 110 through the juice discharge hole 330 and then falls to the lower part of the housing 100 through the liquid discharge port 130. do.

In addition, it is coupled to the front end of the juice pipe 300 and is in close contact with the rear end of the drum cap 200 and the rear end of the contact member 430 to be described later, has a ring shape with a hollow penetrating front and back, and is made of an elastic material to enable elastic deformation. It may further include a ring-shaped front sealing member 350 made of (rubber, silicone, etc.).

For example, when the juice pipe 300 is coupled through the front of the flow path 110 and the rear end of the drum cap 200 is coupled to the front end of the housing 100, the front end of the juice pipe 300 is connected to the drum cap. It can be in close contact with the rear of the juice pipe 300, the juice passage 310 of the juice pipe 300 and the passage 210 of the drum cap 200 can be communicated on the same line, and the front end of the front sealing member 350 The front end of the juice pipe 300 and the rear end of the contact member 430, which will be described later, may be in close contact with each other.

The finishing cap 400 is coupled to the front end of the drum cap 200, and a cylindrical connector 410 protrudes rearward, and a waste discharge port 420 penetrating before and after the connector 410 is connected to the juice passage 310. ) is connected to. Here, the finishing cap 400 can be manufactured using a metal material such as stainless steel, and the number and shape of the waste discharge ports 420 can be variously applied according to need.

In addition, it may further include a plurality of pressure adjustment holes 220 that penetrate in the front and rear directions of the finishing cap 400 and are located radially based on the penetration direction of the connection pipe 410, and of the finishing cap 400. The discharge pressure of the waste discharge port 420 can be variably adjusted by adjusting the open area of the pressure control hole 220 through position adjustment.

For example, when the closing cap 400 is rotated in the locking direction, the gap between the rear of the closing cap 400 and the front of the drop cap 200 is reduced, thereby reducing the area where the pressure adjustment hole 220 is opened. When the closing cap 400 is rotated in the unlocking direction, the gap between the rear of the closing cap 400 and the front of the drop cap 200 increases, thereby increasing the area where the pressure adjustment hole 220 is opened. can be increased.

The juicer according to an embodiment of the present invention is coupled to the inner peripheral surface of the connection pipe 410, has a cylindrical shape with a waste discharge port 420 penetrated forward and backward, and has a contact member 430 made of a plastic material. It may further include. The contact member 430 is a part where the cutting blade 600, which will be described later, comes into close contact with the cutting blade 600 so that it can slide and rotate. Materials such as polyacetal can be used, but the contact member 430 can selectively use various materials as needed. there is.

The rear end of this contact member 430 protrudes toward the rear end of the connection pipe 410 and may be in close contact with the front end of the front sealing member 350. That is, since the gap between the rear end of the contact member 430 and the front sealing member 350 is sealed, residues (S), moisture, etc. moving along the juice passage 310 and the residue discharge port 420 are sealed against the contact member 430. It does not leak out through the gap between the juice pipe 300 and the juice pipe 300.

The contact member 430 according to an embodiment of the present invention is coupled to the inner peripheral surface of the connection pipe 410 as shown in FIGS. 3 to 6, and includes a cylindrical insertion portion 431 through which the waste discharge port 420 penetrates forward and backward, and , It may include a locking portion 432 that extends radially from the rear end of the insertion portion 431 and is caught at the rear end of the connection pipe 410, the rear end of which is in close contact with the front end of the front sealing member 350.

The insertion portion 431 can be coupled with its outer peripheral surface in close contact with the inner peripheral surface of the finishing cap 400, and can be coupled and separated through the rear of the closing cap 400. The locking portion 432 is positioned at the rear end of the connection pipe 410, and the rear end is in close contact with the front end of the front sealing member 350, so that it can seal the gap between the rear end of the contact member 430 and the juice pipe 300. , and residues (S) and moisture moving along the juice passage 310 and the residue discharge port 420 do not leak out through the gap between the contact member 430 and the juice pipe 300.

In addition, a cutting blade 600, which will be described later, is inserted into the inside of the waste discharge port 440 penetrating before and after the insertion portion 431 so as to be able to rotate forward, and when the screw 500, which will be described later, rotates, the cutting blade 600 As both ends in the longitudinal direction are rotated in close contact with the inner peripheral surface of the insertion portion 431, the waste S can be discharged forward.

For example, after separating the finishing cap 400 from the drum cap 200, the insertion part 431 can be pushed into the inside of the waste discharge port 420 through the rear of the finishing cap 400 and coupled in a sliding manner. When the coupling is completed, the front end of the engaging portion 432 may be positioned at the rear end of the connector 410.

On the other hand, the insertion part 431 can be separated from the rear of the closing cap 400 while holding the locking part 432. That is, when the inner peripheral surface of the waste discharge port 420 formed inside the contact member 430 is damaged due to wear, etc., it can be easily coupled and separated by sliding, making maintenance convenient.

In addition, a plurality of outer locking protrusions 240 protrude from the front outer peripheral surface of the drum cap 200 and are spaced apart along the outer peripheral surface of the drum cap 200, and protrude from the inner peripheral surface of the finishing cap 400. , It may further include a plurality of inner locking protrusions 440 arranged in a spaced apart state along the inner peripheral surface of the finishing cap 400.

The outer locking protrusion 240 of the drum cap 200 may have a length along the locking rotation direction of the finishing cap 400, and may have a shape in which the thickness in the front-back direction gradually increases toward one side in the circumferential direction, A locking protrusion may protrude rearward at one rear end in the longitudinal direction of the outer locking protrusion 240.

When the closing cap 400 is coupled to the front end of the drum cap 200, the inner locking protrusion 440 of the closing cap 400 passes through the gap between the outer locking protrusions 240 and secures the closing cap 400. When rotated in the locking direction, it is caught at the rear end of the outer locking protrusion 240, and the closing cap 400 is caught at the front end of the drum cap 200 by being caught by the outer locking protrusion 240 and the inner locking protrusion 440. Stay connected.

In this state, when the closing cap 400 is rotated in the locking direction, the inner locking protrusion 240 slides obliquely along the longitudinal direction of the outer locking protrusion 240 and at the same time, the closing cap 400 moves toward the drum cap 200. It can be moved in the direction facing the. On the other hand, when the closing cap 400 is rotated in the unlocking direction, the inner locking protrusion 240 slides obliquely along the longitudinal direction of the outer locking protrusion 240, and at the same time, the closing cap 400 is spaced apart from the drum cap 200. It can be moved in any direction.

One or more second locking grooves 435 concavely formed at the rear end of the pipe 410, and one or more second locking protrusions that protrude from the front end of the locking portion 432 and are inserted correspondingly into the second locking grooves 435. (436) may be further included.

The first stopping protrusion 434 may have a shape whose diameter gradually decreases as the protruding front end moves forward. That is, since the first locking protrusion 434 is positioned in the front-back direction when inserted into the first locking groove 433, the insertion portion 431 coupled to the inside of the finishing cap 400 does not move in the front-back direction.

In addition, since the protruding end of the second locking protrusion 436 is inserted into the second locking groove 435 and is positioned so that the insertion portion 431 and the locking portion 432 are based on the horizontal rotation center in the forward and backward directions. does not rotate. That is, since the first locking protrusion 431 is locked in the front-back direction and the second locking protrusion 436 is locked in the radial direction, it is possible to prevent the contact member 430 from leaving and rotating.

For example, when the insertion part 431 is pushed into the inside of the waste discharge port 420 through the rear of the finishing cap 400 and coupled in a sliding manner, the first locking protrusion 431 is attached to the finishing cap 400. After being moved in close contact with the inner peripheral surface, it is inserted corresponding to the first locking groove 433 by the elastic restoring force of the insertion portion 431, and the second locking protrusion 436 is positioned corresponding to the second locking groove 435. is inserted.

Since the outer circumferential surface of the rotating body 439b is supported to be able to slide and rotate by a ball member, it can rotate forward and backward in the circumferential direction based on the horizontal center of rotation, and the waste discharge port 440 penetrates the front and back of the rotating body 439b. A cutting blade 600, which will be described later, is inserted to be able to rotate forward.

For example, when the screw 500, which will be described later, rotates, both longitudinal ends of the cutting blade 600 rotate together in close contact with the inner peripheral surface of the rotating body 439b, thereby discharging the waste S forward. , Since the rotating body 439b rotates together with the cutting blade 600 and supports both sides of the cutting blade 600 in the longitudinal direction, distortion (sag, etc.) of the screw 500 can be prevented.

The screw 500 is intended to move the food material 10 forward and pressurize it at the same time through rotation, and is rotatable within the juice passage 310 based on the horizontal center of rotation (C) in the forward and backward directions, and in the axial direction. A spiral protrusion 510 may protrude from the outer circumferential surface so as to extend along a spiral.

Here, the rear end of the screw 500 can be rotatably coupled to the rear of the passage 110, and the front end of the screw 500 is horizontally inserted into the juice passage 310 through the rear of the juice pipe 300. The rear area of the screw 500 may be located in the lower area of the inlet 120. When the food material 10 is introduced into the flow path 110 through the inlet 120, the food material 10 may be seated in the rear area of the screw 500.

The spiral protrusion 510 may be formed along the front-back direction while forming a spiral along the radial direction of the screw 500. That is, when the screw 500 is rotated, the helical protrusion 510 can be rotated to move the food material 10 seated in the rear area of the screw 500 forward, and the outer peripheral surface of the screw 500 and the juice pipe 300 ) The food material 10, which moves forward along the inner peripheral surface of the juice passage 310, is pulverized and pressed by the rotation of the spiral protrusion 510 and the relative rotation of the cutting protrusion 320 and moves forward of the juice passage 310.

In this process, the juice L generated from the planting passage 10 is discharged into the inside of the passage 110 through the juice discharge hole 330, is guided downwardly to the rear of the juice passage 310, and then flows into the passage. The juice (L) that falls to the bottom of the 110 and the lower part of the flow path 110 is discharged to the lower part of the housing 100 through the liquid outlet 130.

The cutting blade 600 is a part that is slidably and rotatably coupled to the inner peripheral surface of the contact member 430. It protrudes from the front end of the screw 500 and has a length in the radial direction of the screw 500, and both ends in the longitudinal direction are waste discharge ports. It is in close contact with the inner circumferential surface of (420) so as to be able to slide and rotate, and is provided to rotate forward based on the horizontal rotation center of the screw (500).

Here, the longitudinal and widthwise rotation centers of the cutting blade 600 are located on the same line as the rotation center of the screw 500, and when the screw 500 is rotated, the cutting blade 600 rotates together and the screw 500 ) supports the front end horizontally, and the width direction of the cutting blade 600 cuts the waste S flowing into the waste discharge port 420 and discharges it to the front of the waste discharge port 420.

In addition, the cutting blade 600 may further include a pair of contact surfaces 610 that protrude from both ends in the longitudinal direction and are curved on both sides in the width direction to correspond to the inner peripheral surface of the waste discharge port 420. Since the contact surface 610 forms a curved surface corresponding to the inner peripheral surface of the waste discharge port 420, when the screw 500 rotates, the cutting blade 600 can be rotated in a state of clear contact.

That is, since the contact surface 610 forms a curved surface corresponding to the inner peripheral surface of the waste discharge port 420, the friction between the contact surface 610 and the waste discharge port 420 can be reduced, and the friction between the contact surface 610 and the waste discharge port 420 can be reduced. The contact area can be increased, enabling stable rotation, and since no significant pressing force is applied to the inner circumferential surface of the waste discharge port 420, noise generation when the cutting blade 600 rotates can be minimized.

In addition, as shown in FIG. 7, it may further include a pair of guide grooves 620 that are concavely formed on both sides of the cutting blade 600 in the width direction and form a curved surface in the longitudinal direction of the cutting blade 600. Since the guide grooves 620 are concavely formed on both sides of the cutting blade 600 in the width direction, the thickness of the cutting blade 600 in the width direction can be reduced, and the waste discharge port 420 is opened by the guide grooves 620. Since the cross-sectional area can be increased, the waste S of the food material 10 can be smoothly discharged.

In addition, as shown in FIG. 8, the cutting blade 600 may extend forward while forming a spiral on both sides of the longitudinal direction in the direction opposite to the rotation direction of the screw 500, and the cutting blade located in the rotation direction of the screw 500 One side of 600 in the width direction can cut the waste (S) and push it forward. In this case, one side in the width direction of the cutting blade 600 located in the rotation direction of the screw 500 can push the debris (S) flowing into the debris discharge port 420 in a diagonal direction and discharge it toward the front of the debris discharge port 420. This can improve the waste discharge performance.

In addition, as shown in Figure 10, the front end of the cutting blade 600 may have a shape in which the width in the longitudinal direction gradually decreases as it moves forward, and the front end of the cutting blade 600 extends obliquely forward from both longitudinal ends of the cutting blade 600 and is connected to each other. A pair of inclined surfaces 630 may be formed, respectively.

At this time, the rear ends of the inclined surfaces 630 may form an angle in a diagonal direction with the horizontal rotation center of the cutting blade 600, and the front ends of the inclined surfaces 630 may be connected to each other on the same line as the horizontal rotation center. That is, since the front end of the cutting blade 600 is formed to have a narrow width by the inclined surfaces 630, the front end of the cutting blade 600 can be easily inserted through the rear of the waste discharge port 420, and the front end of the screw 500 The closing cap 400 can be easily coupled to the.

The cutting blade 600 according to an embodiment of the present invention protrudes from both sides in the width direction of the cutting blade 600 as shown in FIG. 9, intersects at an angle perpendicular to the cutting blade 600, and has waste discharge ports at both ends in the longitudinal direction. It may further include an auxiliary cutting blade 640 that slides and rotates in close contact with the inner peripheral surface of 420).

Here, the auxiliary cutting blade 640 protrudes from both ends in the longitudinal direction and may further include a pair of contact surfaces curved on both sides in the width direction to correspond to the inner peripheral surface of the waste discharge port 420, and the auxiliary cutting blade 640 ) The contact surface forms a curved surface corresponding to the inner peripheral surface of the waste discharge port 420, so when the screw 500 rotates, the cutting blade 600 can be rotated in a state of contact with the surface.

That is, since both longitudinal ends of the cutting blade 600 and both longitudinal ends of the auxiliary cutting blade 640 are in close contact with the inner peripheral surface of the waste discharge port 420, the contact area of the cutting blade 600 can be increased, and 90 Since it rotates while supporting each of the four points located in the angular direction, stable rotation is possible.

On the other hand, the juicer according to the present invention has a main body 20 to which the rear end of the housing 100 is coupled and the lower end is seated on the installation surface, and a rotational force at the rear end of the screw 500, which is installed inside the main body 20 and will be described later. It may further include a driving unit (motor, etc., 700) that transmits and a control unit 30 that is electrically connected to an external power supply (not shown) to control the driving of the driving unit 700.

The main body 20 may have a coupling member penetrated in the front and rear directions on the front, and a corresponding coupling structure may be applied to the inner peripheral surface of the coupling member and the rear end of the housing 100, respectively. For example, after inserting the rear end of the housing 100 horizontally through the coupler, each coupler can be placed into a locked position by rotating the housing 100 in the locking direction, and rotating the housing 100 in the unlocking direction. Each coupler can be separated by rotating it.

In addition, it protrudes forward from the main body 20 and is seated on the installation surface, is electrically connected to the support portion 21 where the liquid outlet 130 of the housing 100 is located at the top, and the control portion 30, and is electrically connected to the user. It may further include a manipulation unit 31 provided on the outer surface of the main body 20 to control the driving unit 700, and the driving unit 700 can be turned on/off using the manipulation unit 31. (OFF) or the rotation speed of the screw 500 can be adjusted.

In addition, a rotating shaft connected from the rear end of the screw 500, a shaft coupling hole 140 that penetrates back and forth through the rear of the housing 100 and into which the rear end of the rotating shaft is rotatably inserted, and an inner peripheral surface of the shaft coupling hole 140. It may further include a ring-shaped rear sealing member 150 that is coupled correspondingly and whose hollow hole penetrates front and back so that the rear end of the screw 500 can rotatably penetrate.

The rear sealing member 150 has an outer circumferential surface in close contact with the inner circumferential surface of the shaft coupling hole 140, an inner circumferential surface is in close contact with the outer circumferential surface of the rotating shaft, and may be made of an elastic material (rubber, silicone, etc.) to enable elastic deformation. That is, since the gap between the shaft coupling hole 140 and the rotating shaft is sealed by the rear sealing member 150, debris (S), moisture, etc. do not leak through the gap between the shaft coupling hole 140 and the rotating shaft.

Additionally, a close contact protrusion 151 may protrude from the inner peripheral surface of the rear sealing member 150. The close contact protrusions 151 may be continuously formed along the inner peripheral surface of the rear sealing member 150 and may be in close contact with them along the radial direction of the rotation axis, and may be arranged in a plurality in a spaced apart state along the axial direction of the rotation axis. In this case, since the inner peripheral surfaces of the contact protrusions 151 are in close elastic contact with the radial direction of the rotating shaft, debris (S), moisture, etc. do not leak out into the gap between the rear sealing member 150 and the rotating shaft.

Hereinafter, the operation of the juicer according to the present invention will be described with reference to FIGS. 1 to 3, and the same configurations as those described above will not be repeatedly described.

First, when the driving unit 700 is switched to the driving ON state using the operating unit 31, the screw 500 and the cutting blade 600 are rotated together by the rotational force transmitted from the driving unit 700. At this time, the spiral protrusion 510 of the screw 500 rotates spirally, and the cutting blade 600 rotates inside the waste discharge port 420.

Thereafter, when the food material 10 is injected into the flow path 110 through the inlet 120, the food material 10 seated in the rear area of the screw 500 is moved forward by the rotation of the spiral protrusion 510. , the food material 10 moved forward by the rotation of the spiral protrusion 510 is forced to move while being pressed through the gap between the juice passage 310 and the screw 500.

At this time, the food material 10 is pulverized and pressed by the relative rotation of the spiral protrusion 510 and the cutting protrusion 320 and moves forward, and a portion of the juice L generated from the food material 10 flows into the juice discharge hole. The juice (L) falls to the lower part of the flow path 110 through (330) and moves downward toward the liquid discharge port 130, and the juice (L), which moves downwardly backward by gravity, flows to the upper part of the inflow-side discharge network 340. It may fall.

In this process, the juice liquid (L) is discharged through the liquid discharge port 130, and the residue (S) of the food material 10 from which the moisture has been removed is drawn into the interior of the residue discharge port 420 by the pressing force of the screw 500. The cutting blade 600, which moves and rotates together with the screw 500, cuts the debris S and discharges it to the front of the debris discharge port 420.

As a result, the present invention can prevent twisting (sag, etc.) of the screw 500 due to its own weight, thereby reducing rotational vibration and noise, and removing the residue S of the food material 10 generated during the juicing process through the screw. The discharge structure of the device can be simplified as it can be discharged in the axial direction of (500), and the waste (S) can be cut to a certain length by the cutting blade (600), making it easy to collect and dispose of the waste (S). do.

In addition, in the present invention, since the cutting blade 600 rotates in close contact with the contact member 430 using a plastic material, the rotation noise of the screw 500 and the generation of metal powder can be minimized, and the food material 10 residue can be minimized. Since the cutting blade 600 is rotated in the process of discharging (S), clogging of the debris discharge port 420 does not occur, and the rotational grinding action of the cutting blade 600 is continuous, thereby reducing the particle size of the debris (S). You can do it.
